Q-Chat
Socratic AI Tutor
When ChatGPT launched, students started using it for homework. But there was a problem: they weren't learning. Getting answers immediately short-circuits the learning process. Quizlet needed AI that would guide students to discover answers themselves.
Student asks: "What's the capital of France?"
The capital of France is Paris.
Good question! France is in Western Europe. What major city do you know that's famous for the Eiffel Tower?
Principle: Guide discovery, don't give answers
Student asks: "I don't understand photosynthesis."
Photosynthesis is the process by which plants convert light energy into chemical energy.
Let's break it down. Plants need energy to grow. Where do you think they get that energy from?
Principle: Scaffold from what they know

"Q-Chat represents what AI in education should be. It's not about giving students answers faster—it's about helping them think better. The misconception detection alone is worth it. Teachers can now see exactly where students struggle and intervene at the right moment."
